* fix(router): persist global retry_policy via /config/update (LIT-3152)
The Admin UI Model Retry Settings tab POSTs
{router_settings: {retry_policy: {...}}} to /config/update, but the
field was dropped on two write-side layers so it never reached the
router. UpdateRouterConfig did not declare retry_policy, so
dict(exclude_none=True) stripped it before the DB upsert. And even when
fed directly, Router.update_settings had no "retry_policy" entry in
_allowed_settings, so the assignment was a silent no-op. The DB row
stayed at {"model_group_alias": {}}, llm_router.retry_policy stayed
None, and the UI fell back to defaultRetry = num_retries = 2 on refresh.
Declare retry_policy on UpdateRouterConfig as a plain dict, and add a
retry_policy branch to update_settings that coerces dict payloads to
RetryPolicy before setattr, mirroring Router.__init__. get_settings
already lists retry_policy, so reads work once writes land.
* fix(router): guard retry_policy type in update_settings
Mirror Router.__init__ semantics in update_settings: only assign
retry_policy when it is None or a RetryPolicy (after dict coercion).
Previously a non-dict, non-RetryPolicy value (e.g. a YAML typo like
retry_policy: 5 flowing through /config/update) was stored verbatim,
deferring the failure to request time in get_num_retries_from_retry_policy
instead of being dropped at write time.
* refactor(ui): harden Model Retry Settings flow and validate retry_policy at the boundary
Types UpdateRouterConfig.retry_policy as RetryPolicy and model_group_retry_policy as Dict[str, RetryPolicy] so /config/update validates the payload and rejects malformed counts instead of silently persisting them; the apply path in update_settings keeps coercing the stored dict back to RetryPolicy
Makes the Model Retry Settings tab the single owner of retry_policy and model_group_retry_policy so the generic Router Settings page no longer renders or writes them, replaces the fire-and-forget save with a react-query mutation that only shows the success toast after the write resolves, surfaces real errors, disables Save while in flight, and re-reads authoritative state on success, and sends both the global and per-group policies atomically so edits in the inactive scope are no longer dropped
Decouples the retry-scope selector from the All Models filter and defaults it to Global, seeds the displayed default from num_retries (falling back to 2), and gives per-group rows real inherit semantics so an empty input shows the global value as a placeholder with a Reset control, keeping 0 ("no retries") distinct from inheriting the global value
* fix(keys): align router_settings examples with typed RetryPolicy and resync UI artifacts
model_group_retry_policy is now Dict[str, RetryPolicy], so the {"max_retries": 5} sample in the key-generate test and the /key/generate and /key/update docstrings no longer validate; they now use a valid {"gpt-4": {"RateLimitErrorRetries": 5}} shape.
Regenerated eslint-metrics.json (no-explicit-any drifted 2027 -> 2026) and schema.d.ts (new RetryPolicy schema, retry_policy field, model_group_retry_policy value type) so the UI build and api-types-sync checks pass
* test(router): pin retry_policy persistence end to end (LIT-3152)
The existing retry_policy tests exercise UpdateRouterConfig and Router.update_settings in isolation, so they would all still pass if a regression flipped ConfigYAML.router_settings back to a loose dict or stopped add_deployment from applying the stored row. This drives the real handler chain an Admin UI save triggers: update_config writes the LiteLLM_Config row, the apply path forwards it to the live router, and get_config serializes it back, pinning retry_policy across persist, apply, and read-back.
* fix(teams): use valid model_group_retry_policy example in router_settings docstring
Same stale {"max_retries": 5} example the key endpoints carried; model_group_retry_policy maps a model group to a RetryPolicy, so the team /team/new and /team/update docs now show {"gpt-4": {"RateLimitErrorRetries": 5}}. Regenerated schema.d.ts to match.
* fix(ui): load retry settings via deferred fetch to satisfy set-state-in-effect
The Model Retry Settings effect called loadRetrySettings synchronously; eslint-plugin-react-hooks (react-hooks/set-state-in-effect) traces into it and flags the setState calls, failing frontend-lint. Split the loader into fetchRouterSettings + applyRouterSettings and run the fetch in an inline async IIFE with a cancellation flag, so state is applied in the post-await callback rather than on the effect's synchronous path. Behavior is unchanged and onSuccess still refreshes via loadRetrySettings.
* fix(ui): match CI rendering of RateLimitError 429 docstring in generated schema
gen:api run on a dev env (python 3.13 / newer fastapi) rendered the RateLimitError response description with 4-space indentation, but CI regenerates it with 8-space under its frozen python 3.12 toolchain, which is the canonical committed form. The Check UI API Types Sync job regenerates and diffs, so restore that block to the CI rendering; verified byte-identical to the pre-existing committed version.
* fix(ui): pin RateLimitError 429 docstring to CI's frozen schema rendering
Base #29619 regenerated schema.d.ts on a newer FastAPI that renders the RateLimitError response description at 4-space indent, but the Check UI API Types Sync job regenerates under the frozen python 3.12 toolchain, which renders 8-space. Merging base pulled in the 4-space form; restore the 8-space rendering so the generated types match what CI produces (verified byte-identical to the pre-#29619 committed form), which also corrects the base drift once this PR merges.

Testing for litellm/
This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.
The point of this is to:
- Increase test coverage of
litellm/ - Make it easy for contributors to add tests for the
litellm/package and easily run tests without needing LLM API keys.
